Synopsis: High pressure currently centered near the Louisiana coast will gradually move into the eastern Gulf of Mexico by this evening, continuing eastward across North Florida on Sunday, then on to near Bermuda by late Monday. Meanwhile, low pressure will start to develop in the far western Gulf early next week, causing southeast breezes to freshen and become occasionally strong. A brief lull is expected Wednesday night into Thursday in advance of a cold front. Winds quickly freshen once again sometime Thursday night or Friday morning in the wake of the next frontal passage.
